Abstract
A ceramic filter comprising a plurality of three-terminal, dual-mode ceramic filter elements which are connected with each other through a capacitive coupling circuit which is adapted to increase the input/output impedance of the ceramic filter.
Claims7
A ceramic filter including at least two three-terminal, dual-mode ceramic filter elements each having an input and an output and a ground connection, and a capacitive coupling circuit comprising first capacitive means connected between the input of one of said filter elements and the output of the other of said filter elements and second capacitive means connected between said first capacitive means and the respective ground connection.
